(cont) I do however warn my customers to keep the ozone level down, don't use air fresheners (which are poisoins to begin with) or pine sol due to the chemical interactions but I have yet to have an issue since.

Ecoquest is successful because they let people try before they buy and the product has brought relief to 7 million people. That is why EQ is the largest Healthier living technology co in the world and their revenues are steadily increasing by 25-50% each year continuously. They expect to break the billion dollar mark within 10 yrs. In 7 they went from bankrupt to almost a fortune 500 as they were before.
